AWS Lambda with External Dependencies

When building modern serverless applications, you rarely write everything from scratch. To build powerful AWS Lambda functions, you must know how to integrate external dependencies and third-party libraries efficiently. This text-based course guides you through the entire lifecycle of managing external packages within your serverless environment. You will start with the absolute basics of serverless architecture and package management before moving into hands-on configuration. Learn how to structure your project directory, handle node_modules, and use Lambda Layers to keep your deployment packages lightweight and reusable. We also cover modern best practices, including security scanning for dependencies and optimizing package sizes for faster cold starts. What you will learn: Understand how AWS Lambda executes code and manages runtime environments; Package external dependencies and npm libraries alongside your function code; Configure Lambda Layers to share common libraries across multiple functions; Optimize deployment package sizes to improve performance and reduce cold start latency; Apply security best practices to audit and secure your external dependencies. The course begins with foundational concepts of serverless environments and dependency trees, then moves systematically through packaging strategies, layer configuration, and optimization techniques. This course is designed for web developers and cloud beginners who want to write clean, production-ready serverless code. No prior AWS packaging experience is required.
